For the next set of results, we use the Gilbert-Elliot model [1]}  for the request arrival process. The parameters of the model are as shown in Figure REF . The request arrival process is Poisson(200) when the Markov chain is in high state (H), and Poisson(10) in the low state (L). The values of partial storage \(\alpha \)  and forwarding cost \(g(\alpha )\)  used here are chosen based on a curve derived from a real dataset (see Figure REF ); details are presented in Section REF . From Figure REF , we see when \(\alpha =0.16\) , forward cost \(g(0.16)\)  is \(0.76\)  which is the minimum \(\alpha + g(\alpha )\)  pair among all pairs.
